QARRIER SEPARATOR FOR PNEUMATlC-TUB E APPARATUS.

To It II /1 m it may (:olmwrrt:

Be it known that I, (Ynnsrnu S. Jsnxrxcs,

of Brookline, in the county of Norfolk and State of Massachusetts, have invented eertain new and useful Improvements in Carrier-Separators for Pneumatic-Tube Apparatus, of which the following is a specification.

My invention relates to improvements in carrier separators for pneumatic despatch 1o tubeapparatus, and its object is to produce a simple, positive and automatic device for separating carriers in transit in said apparatus and enable said carriers to be properly switched or delivered thereby preventing the I 5 clogging of the switching mechanism.

In theaccompanying drawings which illustrate a construction embodying my invention, Figure 1 is a longitudinal section of the device attached to a pneumatic transit tube and showing carriers in operating contact therewith. Fig. 2 is a cross section on line B-B Fig. 1 looking in the direction indicated by the arrow. Fig. 3 is a top plan view partly in section showing operating mechan- 2 5 ism. Fig. 4 is a perspective view of the operating levers.

Like letters of reference refer to like parts throughout the several views:

A represents an ordinary pneumatic transit tube surroumled by the casing B in the upper portion of which is located the chamber (l. Pivoted in said casing B within the chamber C is the shaft I), one end of which projects outside of said casing B. Within 3 5 said chamber and pinned to the shaft D by pins E is the lever F one end of which projects through a slot (1 in the transit tube and into the path of the carriers. The lever F is normally held in position as shown in Fig. 1 4o (dotted lines) by the helical spring G confined between the pin G on the casing B and the pin G on the shaft D. The upward movement of the lever F is limited by the pin H. The yoke lever J is pivoted on the shaft 4 5 D, the yoke of said lever being mounted outside of the arms F of the lever F. Mounted on the shaft D and between the arms F is the helical spring K fixed at one end to said shaft by a pin K, the opposite end K of said 5o spring pressing upon the top of the lever J and adapted to hold-the inner face of the yoke on said lever against the lugs F of the lever F. This permits the lever J to be flexi- Specification of Letters Patent.

1 blein one direction only, the pin L limiting the movement in that direction at the same time limiting the projection of the free end of the lever F into the tube A. The slot .0 in the tube A permits of the de ression of the free end of the lever J into said tube.

The operation is as follows: The carrier S in transit through the tube A in the direction indicated by the arrow, strikes the free end of the lever F raising said lever against the ten: sion of the spring G from its normal position shown by the lower dotted lines. At the same time, the leverJ heldagainst thelugs F b'y'the spring K is depressed from the position shown by the upper dotted lines to the position shown in full lines. The carrier S is now in the position shown in Fig. 1. A further movement of the carrier causes the lever F to be raised to the position shown in upper dotted lines and against the stopI-I, permitting the further depression of the lever J to the position shown by the lower dotted lines and in position to engage the following carrier S. In the meantime, the carrier S holds the levers F and J in said position checking the passage of the carrier S until said carrier S has passed out of operating contact with the lever F when the mechanism will immediately resume its normal position releasing the carrier S. The flexibility of the lever J with relation to the lever F prevents the binding of said lever J upon the operating carrier.

Having thus described the nature of my invention and set forth a construction embodying the same, what- 1 claim as new and desire to secure by Letters Patent of the United States is:

1. In a carrier separator for pneumatic despatch tube apparatus, a tube for the transmission of carriers, a lever projecting into saidtube and adapted to be operated by a carrier in transit, means actuated by said lever for checking the passage of following carriers, and means for automatically releasing the following carriers after said operating carrier has passed out of contact with said lever.

2. In a carrier separator for pneumatic despatch tube apparatus, a tube for the transmission of carriers, a casing surrounding said tube, a lever pivoted to said casing and projecting into said tube and adapted to be operated by a carrier in transit, mechanism ,a carrier in transit, mechanism actuated by said lever and adapted to be depressed into said tube after the passage of the operating carrier thereby checking the passage of the following carrier, yielding means adapted to prevent the binding of said mechanism upon said operating carrier, and means for automatically releasing the following carriers after said operating carrier has'passed out of contactiwith said lever.

4. In a carrier separator for pneumatic 'despatch tube apparatus, a tube for the transmission of carriers, a casing mounted on said tube, an opening connecting said casing with said transmission tube, a trip lever pivoted'in said casing and normally projecting through said opening into said tube and adapted to be lifted by a carrier in transit, a'

spring adapted to hold said trip lever in normal position, a check lever pivoted in said casing co-incident with said trip lever and adapted to be depressed by said trip lever through said opening into said tube immediately after the passage of the operating carrier whereby following carriers are checked, yielding means connecting said trip lever with said check lever adapted to preventl binding of said levers upon the operating carrier, and means for releasing the following carriers after said. operating carrier has passed out of contact with said trip lever.

5. In a carrier separator for pneumatic despatch tube apparatus, a tube for the transmission of carriers, a casing mounted on said tube, an opening connecting said casing with said transmission tube, a trip-lever pivoted in said casing and normally projecting through said opening into said tube and adapted to be lifted by a carrier in transit, a spring'adapted to hold said trip-lever-in normal position, a check-lever pivoted insaid casing co-incident with said trip-lever and adapted to be depressed by said trip lever through said opening into said tube immediately after the passage of the operating carrier whereby following carriers are checked,

yielding means connecting said trip-lever with said check-lever adapted to prevent binding of said levers upon the operating carrier, means for releasing'the following carriers after said operating carrier has passed out of contact with said tr1plever, and

means for'limiting the movement of said levers.

In testimony whereof, I have'signed my name to this specification in the presence of two subscribing Witnesses, this nineteenth day of June A. D. 1906.
